LUBRICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 326,304, datedSeptember 15, 1885.

Application died July 8, 1885. (No model.)

.To all whom it may concern:

Be it known that I, CURTIs M. LONG, of Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented certain LubricatingApparatus, of which the following is a specification.

I design my lubricating apparatus particularly to be used in engines ofthe class having oscillating pistons; but it is applicable to variousother uses.

In the accompanying drawings, illustrating my improvements, Figure 1 isa side eleva' tion, partly in section, of such an engine. Fig. 2 is asectional view drawn on a larger scale, showing the details of myinvention and its made of operation.

Referring to the letters upon the drawings, A indicates the hollowcasing or support containing the working parts of the engine and of thelubricating apparatus below.

B indicates an oil-inlet pipe, through which water or oil, or both, canbe admitted. This pipe is perforated at O, as indicated, the upperperforations being intended to be above the water-line for the admissionof oil, and being a little larger than the lower ones for the admissionof water, which are to be below the water-line.

D indicates the water-line, and E the oil above it. Instead of havingthe inlet-pipeB extend above the oil, it might be cut ed at about thewater-line, so as to let the oil flowiu at its open end, and the waterflow in at the perforations below the watcr-1ine. This would be only-aformal variation embodying the principle of action that I contemplate,which is that the oil mingled with water shall be admitted through alower continuation of the pipe 13 into the cup F through valve G in itsbottom. The valve G is of ordinary construction, so as to be normallyclosed by its own weight.

H indicates a flexible diaphragm secured around the rim of the cup bymeans of screwnnt I, as indicated, or in any usual or suitable manner.

K indicates a rod connected with an eccentric, L, working upon the maincrank-shaft M of the engine, so as to operate the rod and vibrate thediaphragm in the manner of thumb pressure upon the bottom of an ordinarysmall oil-can.

N indicates a pipe or passage from the oilcup outward. This passage isprovided with a ball-valve, O, normally tending to close it M bygravity.

P is a screw-cap fitting over the outer end of the pipe, as shown, andserving to keep the ball-valve from getting out of place.

Q indicates jet pipes or nozzles extending out of the screw-cap, anddirected toward different parts of machinery to be supplied withoil-jets and lubricated.

It will be observed that thislubricating apparatus islocated in thebottom of the engine case, where it is inclosed like the engine itself.

The theory and practical operation of my improved apparatus are asfollows: The water being placed in the engine-case through any suitableopening for the purpose, so as to cover the lubricating apparatus aboutas indicated in the drawings, the oil is next poured in through anopening in the casing, so as to float upon the water about as indicatedin the drawings. Now, the engine hcingstarted, the diaphragm of theoil-cup will immediately force the contents of the cap (which fora fewstrokes may be water) out through the jetting apparatus onto the workingparts of the engine, the valve G being closed by each downward movementof the diaphragm, and the ball-valve being raised and opened at the'sametiiue. As the diaphragm rises, the valve G will be opened, theball-valve will be closed, and the mingled oil and water will be drawnby suction into the cup. Each successive complete vibration of thediaphragm thus serves to fill and partially empty the cup in the sameway. The vibrations being quite rapid, the oil and water intermingle byagitation and pressure and flow into the cup, and thus a continuouscirculation is kept up.

In the operation of the engine there will be constantly some watersupplied by condensation, which itis necessary occasionally to draw off,so as to preserve the water-line about as indicated. I therefore providean ordinary water-cock, R, for this purpose. The water, being heavierand at the bottom, may be drawn oft without material waste of the oil.The oil and water jet upon the engine will drip back and be againjetted, and so on continuously, so that a single supply of the oil willbe automatically applied to the cngimover and over again with veryslight waste. The oil will only need to be replenished slighty at longintervals. The water serves to keep the oil in position above it whereit may enter the pipe and go to the oil-cup, and also byinterminglingwith the oil it serves to keep the journals of the engine cool, which isa very important matter in high-speed engines.

I do not confine my invention to the details or particular form ofembodiment herein illustrated and described, because the form ofembodiment may be changed without departing from the substance of myinvention.

In order to distinguish my improvements from what has gone before, Iwould say I do not claim, broadly, the use of an oil-jetting apparatussubmerged in liquid within a receptacle and-operated by the mechanism tobe lubricated. Such an apparatus, for example, is shown in United StatesPatent No. 39,059, issued June 30, 1863. My improvements in this classof lubricating apparatus are intended specially to provide for theemployment of mingled oil and water, although they are adapted to theuse of oil alone, and they are confined to the construction and combination of parts specified in my appended claims.

What I claim to be new, and desire to secure by Letters Patent of theUnited States, is-- 1. In combination with a revolving engine or othershaft, a suitable casing or receptacle for liquid, the perforatedinlet-pipe B, the cup F, provided with diaphragm H and jet-pipe, thevalves G and O, and the eccentric and rod for vibrating the diaphragmand agitating and forcing out the liquid, substantially as set forth.

2. In combination with a revolving engine or other shaft, a suitablecasing or receptacle for liquid, the perforated inlet-pipe B, the cup F,provided with inlet and outlet valves G and O, and jet-pipe, theeccentric and rod, and a vibrating diaphragm, or equivalent mechanism,for forcing out the lubricant, substantially as set forth.

45 In testimony whereof I have hereunto subscribed my name.
